Who would an unhappy husband with an unfaithful wife meet on a train? In a Patricia Highsmith novel, a helpful psychopath, naturally. Cuckold Guy gets talking to loopy Bruno and is offered a deal: I'll kill your wife, if you murder my dad; with no connection between us, the police will never track us down.
